Introduction:
Undecanedioic acid, in the form of a white powder or flake, is dibasic acids which is a family of organic compounds, also known as 'long-chain dicarboxylic acids'. Undecanedioic acid is an alpha, omega-dicarboxylic acid that is nonane with two carboxylic acid groups at positions C-1 and C-9. It has a role as a metabolite. It is a conjugate acid of an undecanedioic acid anion. It has recommended applications in corrosion inhibitors, hot melt adhesives, high performance polyamides/nylon, metal-working fluid, lubircant, adhesive, powder coating, and more.
Undecanedioic acid has been found in parts of human aortas with advanced atherosclerotic lesions associated with intercellular matrix macromolecules and specifically with elastin, and may be the result of an increased hydrolysis of esters and (or) a decreased esterification. Undecanedioic acid has been found (among other unusual dicarboxylic acids) in the urine from patients under hopantenate therapy during episodes of Reye's-like syndrome.
Undecanedioic Acid (Aquacor® UDA) is a nitrite-free dibasic acid, which provides excellent ferrous corrosion inhibition properties. It is used in a variety of lubricity & corrosion inhibitor applications , including lubricant oil, lubricant grease, coating powder, metalworking fluids, engine coolants, metal cleaners, aqueous hydraulic fluids, and die cast release agents, it also can be used for polymer new materials. 1.0-5.0%
